石墨烯的尺寸对水泥基材料性能的影响
Effects of graphene dimensions on the properties of cement-based materials
摘要
Abstract
Graphene cement-based materials were prepared using four different sizes of graphene(peeling graphene,PG1,PG2,PG3,and PG4),and the influence of the size of graphene on the hydration properties and mechanical properties of cement-based materials were studied.The test results show that the incorporation of graphene improves the hydration speed of cement and reduces the mobility of the cement slurry,with the most pronounced effects observed for smaller-sized graphene.In terms of mechanical properties,small-sized graphene is beneficial to improve the compressive strength,while large-sized graphene contributes more to improving the counterfolding strength.According to the analysis of XRD(X-ray diffractometer)and SEM(scanning electron microscope),etc.,the incorporation of the four graphene does not change the type of cement hydration products,but it can effectively refine the size of calcium hydroxide(CH)crystal and improve the compactness of cement matrix.The refinement effect on CH crystals becomes more evident with decreasing graphene size.关键词
